Filters for water purification in an apartment - varieties, features. A century ago, a centralized water supply was only in the largest and richest cities. Now he has appeared in every city apartment, and has become an irreplaceable benefit of civilization. But it often happens that the quality of water in a centralized water supply system leaves much to be desired - drinking it is, at least, unpleasant if not boiled.
And in most homes, this is not at all worth doing because of harmful impurities that can lead to problems of the gastrointestinal tract and skin.
In order for water to flow from the tap at home, which will be suitable for drinking, it is required to use special filtering devices. Filters for water purification in an apartment can be of several types, and which ones will be discussed below.
The use of filter-type installations in life gives several pleasant effects:
- Helps to remove harmful impurities from water , which have a very negative effect on the human body, as well as on household appliances - washing machines, kettles and dishwashers.
- Improves palatability . Even if there is a small concentration of harmful substances in the water that you have at home, a small amount of them can still spoil the taste.
- Softens water. The result is that it does not harm the skin of the face and body in general, and the hair is healthier and softer.
We suggest considering what types of products exist.
Filters can be divided into 3 categories according to the type of elements removed from the water:
Let's take a closer look.
A little about the manufacturers
On the Russian market of filtering devices such products are sold from different manufacturers:
A brand of Ukrainian origin, the models are also suitable for installation at the bottom of the sink, there are flow and reverse osmosis.
We suggest that you familiarize yourself with the filters that are cleaned of mechanical impurities.
Installation of such filters for water purification in an apartment is needed in order to purify water from grains of sand, winding from pipes, metal impurities and rust.
Such small impurities cause great harm to household appliances (dishwasher and washing machine, electric kettle), as well as pipeline fittings.
Please note, that there are 2 types of filtering elements, which differ in the type of construction - disc and mesh.
They have a T-shaped (without washing) or cruciform (with washing) body with a long lower part. It is in it that the filter element is located - a fine-mesh mesh cone through which the entire flow passes. All impurities will remain on the mesh, which should be cleaned out as it becomes clogged .
According to the flushing method, there are the following types of models :
- Without flushing - in this case, the area with filters will be closed by means of taps, while the lower part of the housing will be unrolled, the mesh removed and cleaned.
- With flushing - the lower part with filter elements is equipped with a branch pipe with a tap, and a pipe or hose is connected to it, which will be diverted to the sewer. A pressure gauge is usually installed in the upper part of the case, which will indicate if the filter is dirty (if the pressure is lowered, then the filter is definitely clogged). To flush, open the tap located below, and the water pressure will rinse the accumulated impurities directly into the sewer.
Now let's move on to the next view.
Let's move on to the second variety.
In addition to the mechanical type of impurities, water may contain various chemical elements that can change the hardness. They greatly spoil the original taste of water, and at high concentration they can even harm the human body, and are harmful to household appliances, pipeline fittings. With constant drinking of hard water, a person may have a violation of the mineral balance of the body. One of the consequences may be the appearance of kidney stones or urolithiasis.
We are talking about hardness salts - magnesium, potassium, calcium and mercury. In addition, there is often an increased concentration of iron in the water. Filters can differ in the items they remove.These are filters for hardness salts or iron. To choose the right one, for a start it will not be superfluous to hand over tap water for analysis.
Increased concentration number iron is usually found in water from wells and wells. This is much less common in tap water. Iron often gives water a noticeable metallic taste and reddish color. The maximum concentration allowed (determined by laboratory analysis) is 2 mg / liter. If the concentration is higher, you should definitely install a fine filter for the apartment.
It will look like a large cylinder that will be connected to electrical power and water supply. There is always a catalyst and fine gravel inside the body. Water flows through the catalyst bed from top to bottom, and impurities precipitate. In the lower part of the body there is a branch pipe for draining water into the sewer network - through this line, precipitated impurities are removed by a stream of water. From time to time, the catalytic backfill should be replaced, and if necessary, it will be able to purify water not only from iron, but also from chlorine and manganese.
Such equipment will cost about 25,000 rubles, and is usually installed in private homes.
From hardness salts
According to the principle of operation and varieties, such filters are very similar to those described above (made in the form of cylinders with filling) ... The only difference lies in the filter element - there are ion-exchange resins inside, and hardness salts will constantly "stick" to them.
The filling in such a filter can serve you without replacement for 5 to 7 years.
Filters for purifying water to a drinking state
If there is a small concentration of iron, small impurities or hardness salts in the water, then it can be used for domestic and technical purposes (wash dishes, wash clothes and swim). But in order to prepare food and drink, it is suitable only after boiling. To make your tap water more drinkable, be sure to use the filters listed below.
Filtering devices of this type do not fit into the cold water supply system, only tap water is poured into the jug .
Inside there is a cartridge with filtering elements, and the set of elements can include the following:
Externally, the devices are similar to an electric kettle with transparent walls. The volume of most of the models is from 2.5 to 4 liters, and the approximate cost varies from 300 to 900 rubles. By the way, the attachments should be changed regularly, once every 1-3 months (it all depends on the filter, the number of people in the family).
Nozzles for faucet
The approximate cost is from 650 to 1000 rubles.
According to the method of attachment, there are two types of nozzles:
According to the principle of operation, there are the following:
- Adsorption - inside the body there is a porous type of material that absorbs impurities (chemical and mechanical).
- With an ion-exchange membrane and a mesh with fine cells - help to purify water from mechanical impurities (they are retained on the surface of the mesh) and other "unnecessary" compounds.
Average productivity is about 1 liter per minute and approximate nozzle life is 1000 to 3000 liters.
Reverse osmosis filters
Filters for water purification in apartments are different, so we suggest considering a reverse osmosis device. The approximate cost of the device is from 6500 to 9400 rubles.
The device is made of three cones, each of which has a separate filter. The flasks are of a removable type and are attached to the same body. The filter elements inside the flasks can be different (it all depends on the model).
Most often, the composition is approximately the following:
A porous element is used for cleaning.
0001 microns. Nothing but water molecules can pass through them.
By the way, at the third stage, the flow is divided into two parts - clean water (which enters the storage tank, if available, and after that to the tap) and the filtered sediment (which goes to the sewer).
Since the most effective filters are the multistage type filters that are installed under the sink, we suggest considering the rating of the best models ..
|Model name||Description||Estimated cost|
Aquaphor OSMO 50
|Helps soften water, removes turbidity, removes residues of chlorine, nitrates, heavy metals, rust. The disadvantages are relatively noisy operation and slow filtration of the flow.|| |
6 790 rubles
Geyser prestige PM
